Horizontal speed of the ball is given as
height of the ball is given as
now the time taken by the ball to reach the bottom is given as
now we will plug in all values
now the distance from the base is given as
`
so it will land at distance of 40.4 m
1.) Product is a solid
2.) Product has flat slides
3.) Flat sides meet at sharp edges and corners
The product would be a crystal, or it would be a type of product in a crystal structure.
Answer:
Stays the same.
Explanation:
The temperature does not change just because something melts.
v = speed of the source of sound or the train towards the listener or switchman = 40 m/s
V = actual speed of sound = 340 m/s
f = actual frequency of sound as emitted from source or the train = 1000 Hz
f' = frequency as observed by the listener or by switchman = ?
Using Doppler's law , frequency observed by a listener from a source moving towards it is given as
f' = V f /(V - v)
inserting the values
f' = 340 x 1000 /(340 - 40)
f' = 340 x 1000/300
